Using an exponential function, it is found that 4 mg of the substance would still be left after 32 days.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, considering that the initial amount if of 64 mg, and we are working with half-lifes, the equation is given by:

32 days is 32/8 = 4 half-lifes, hence the amount remaining in mg is given by:

Well 1 and 6/12 add 2 and 6/12 gets a total of 4 full hours add this to the 1 and 9/12 this gets 5 and 9/12 60 min /12 is 5 min per part so 5x9 is 45 therfore he ran 5 hour 45 min
give me a sec finna get answer
Answer:
Step-by-step explanation:
1) 
= 50 + (-9*8) *1
= 50 - 9.8
= 40.2 m/s
2) The acceleration of the ball at its maximum height equals to the force of gravity. -9.8 m/s²
3) The velocity at its top of the path:When the ball is thrown straight up, its velocity keeps on decreasing due the pull of gravity which pulls it towards the ground. So, the velocity at the top of its path is zero.
